I recommend to take a look at oscilloscope / - graph images from "square" waves out of different types of sources -i.e. digital and analog (synths and other generator types/sources). By theory, any square wave could be constructed by a infinite number of (sinus) signals, while many of that images seems like produced from a finite number of such "signal parts". this means - if i think correctly - a really perfect square would have "infinite energy" required (pls correct me, if i'm wrong here). A lot of the "subtile timbre" of a synths square wave could be "found" in the (by tech limits / physics always a bit imperfect) "edges" of the squares. i assume if you want to reproduce such "analogish" square in digital, the resulution of the sampling and reproduction at this stage should be important. sorry for possible tech imperfections -my view onto this is more one from a synth user then a DSP specialist. just my .02 niels. -- --- Niels Dettenbach ((db)) dettenbach audio http://dettenbach.com PGP: https://syndicat.com/pub_key.asc --- _______________________________________________ dupswapdrop: music-dsp mailing list firstname.lastname@example.org https://lists.columbia.edu/mailman/listinfo/music-dsp
